-This is MS Paint, Why go Simplistic? If I wanted it simplistic I could easily take off the Portrait you should've put on the wall, or the parallel devil kid's you should've put right next to them, watching them and learning from them.

-Lack of Border & Simple unoriginal Heaven style and poses (obviously you should've tried a different position only possible on 2D).

-No stylish unique signature either...

-No cameo or modern or pre-historic or simply historic subtle rare references

-No dialogue (In a contrasting accent language, ie one speaks southern or jamaican english while the other speaks proper british)

I mean, for fucks sake, this wouldn't land in any self-respecting muesum until it was desperate, and probably then it would just close down instead of acceptign this quality of artwork, Absolutely Pathetic. Kill yoself
